Disclosed are novel 1,2,4-triazin-5-one biphenyl derivatives having structural formula (I) useful as non-peptide antagonists of angiotensin II receptor: where R1 represents alkyl, cycloalkyl, or substituted or unsubstituted aryl; R2 represents alkyl, substituted or unsubstituted aryl, or arylalkyl; A and D independently represent C-R3, N, NH or C=O, wherein when A and D independently denote C-R3 or N, b and c are independently a double bond, and when A and D independently denote NH or C=O, b and c are independently a single bond; provided that b and c are not both double bonds; and R3 is hydrogen, dialkylphosphonate or halogen; and pharmaceutically acceptable salts thereof. Also disclosed is the use of the compounds of formula (I) as non-peptide antagonists of angiotensin II receptor, in the treatment of cardiovascular diseases, in particular hypertension and congestive heart failure.
